Utility model content
(1) technical problem that will solve
The utility model cannot move to overcome existing blackboard, affects the shortcoming of teaching efficiency, and the technical problems to be solved in the utility model is to provide a kind of think of political affairs teaching packaged type small blackboard.
(2) technical scheme
In order to solve the problems of the technologies described above, the utility model provides a kind of like this think of political affairs teaching packaged type small blackboard, includes cylinder, expansion link, sliding sleeve, spill supporting plate, small blackboard, rope, connecting rod, slide block, slide rail;
Be provided with cylinder before classroom, cylinder is connected with expansion link one end, and expansion link is provided with sliding sleeve, expansion link and sliding sleeve are for being flexibly connected, the expansion link other end is connected with spill supporting plate, on spill supporting plate separate type be provided with small blackboard, spill supporting plate is connected with sliding sleeve by rope; Be provided with slide rail above classroom, slide rail is provided with slide block, slide block is connected with connecting rod one end, and the connecting rod other end is connected with sliding sleeve.
Operation principle: think political affairs class hour when preparation is upper, because small blackboard separate type be arranged on spill supporting plate, teacher first can be placed on spill supporting plate the small blackboard finishing writing content, then cylinder is started, cylinder controls expansion link to classroom subsequent motion, expansion link drives the spill supporting plate be attached thereto, and the small blackboard that spill supporting plate is placed is together to classroom subsequent motion, when spill supporting plate and small blackboard move to certain position, spill supporting plate can drive, and the sliding sleeve be attached thereto by rope is also to classroom subsequent motion.
Sliding sleeve is connected with slide block by connecting rod, and sliding sleeve also drives connecting rod to classroom subsequent motion together with slide block, and slide block is arranged on slide rail.The movement of sliding sleeve, connecting rod and slide block, what can prevent expansion link from stretching to classroom below is long, and caused tenesmus bends.
After the think of political affairs that small blackboard is write held within the class period having said, start cylinder, cylinder controls expansion link and drives spill supporting plate and small blackboard to position, the dais motion before classroom, after spill supporting plate and small blackboard move to certain position, spill supporting plate can drive sliding sleeve, and moves to the position, dais before classroom together with the slide block be connected with sliding sleeve by connecting rod.When spill supporting plate and small blackboard get back to origin-location, stop cylinder operation, teacher changes other small blackboard, can carry out reciprocating operation next time.
(3) beneficial effect
